As a low-cost and low-power-consumption passive reflector, intelligent reflecting surface (IRS) can make significant rate improvement by building programmable wireless environment. To improve the performance coverage range of networks, an IRS-aided decode-and-forward (DF) relay network is proposed with multiple antennas at station (RS). achieve high rate, alternately iterative structure (AIS) m...

In this letter, we investigate an outdoor and indoor wireless communication network with the assistance of a relay-aided double-sided reconfigurable intelligent surface (RIS). A scheduling problem is considered at access point (AP) to minimize sum age information (AoI). To serve users further enhance link quality, RIS relay utilized. Since formulated non-convex highly-coupled variables, success...

Under the present regime of globalization and liberalization, quality enhancement and cost reduction are two major steps to enhance productivity in major Industries. We focused on the very practical, safe, economical and rewarding strategies i.e. the application of LOW COST AUTOMATION. In Industry which uses of automation, a sequence is followed in the manufacturing of number of products of the...

Device-to-device (D2D) pairs are allowed to reuse the spectrum of cellular users who are in a good quality channel state with underlaying cellular network. However, cellular users usually suffer a poor performance in term of achievable rate when they are in a cell edge or in deep fading. To solve this problem, a hybrid relay-aided D2D communication scheme with a two-antenna infrastructure and u...

A dual-hop status update system aided by energy-harvesting (EH) relays with finite data and energy buffers is studied in this work. To achieve timely updates, the best should be selected to minimize average age of information (AoI), which a recently proposed metric evaluate freshness. The AoI minimization can formulated as Markov decision process (MDP), but state space for capturing channel buf...

In this contribution we propose and investigate a relay diversity transmission scheme for the direct-sequence code-division multiple-access (DS-CDMA) downlink, where each (destination) mobile terminal (MT) is aided by a cluster of relays for achieving the relay diversity. In the considered system downlink multiuser interference (MUI) is suppressed with the aid of transmitter preprocessing opera...
